Association between copepods and bacteria was observed in many scanning electron micrographs. Particular sites on the copepods were selectively colonized by bacteria; the joints of segments and legs, swimming legs and depressed parts of the body surface were found to be densely covered with bacteria. In comparison, bacterial attachment to copepod skeletons in fecal pellets excreted by chaetognaths was not selective; bacteria were sparsely found all over the copepod. Between 9 to 30% of copepods in Tokyo Bay waters had attached bacteria in January and April 1983.
